Not surprisingly, early explorers in deserts, particularly Europeans travelling in the Sahara from the late 18th century onwards, were impressed by, and reported on, the unusual features of these areas.

This chapter focuses on the morphology, chemistry, mineralogy, and origin of the major types of crusts found in dryland environments. Particular attention is given to
